TL;DR: It is suggested that by generating designs which can be quickly assessed, and through being supplied with advice and assessment as the design proceeds, the designer can improve the design to product cycle.
Abstract: A method of specifying and generating a set of designed objects known to be assessable is proposed. It is suggested that by generating designs which can be quickly assessed, and through being supplied with advice and assessment as the design proceeds, the designer can improve the design to product cycle. The method is based upon attributed graph grammars which specify valid manipulations of feature models in feature-based design. Semantic functions compute and constrain the feature attributes, and generate a simultaneous assessment as the design progresses. Finally, an example within the domain of stress concentration prediction is presented.

TL;DR: This paper suggests how technical limitations in programs currently in use can be overcome to widen the field of application of parametric programs.
Abstract: A parametric program may use rules and algorithms to define the relationships between dimensions and elements of designs, and it may thus generate variants of a design. Programs currently in use have technical limitations in their ability to handle time-varying and imprecise data, the search for suitable existing designs and their maintainability. The paper suggests how these and other limitations can be overcome to widen the field of application of parametric programs.
